Battery question

'Battery Tender' here as well. Love it. Got it to use with my Big Dog Chopper (motorcycle obviously) and kept it when I sold the bike. Now I use it on the Marauder now. Especially since I dont drive it every day.
 
Regardless of battery tender/charger type, it's a good idea, if you have not done so in recent years, to remove battery cables, clean both battery posts & cable ends with fine sand paper, wipe done with solvent, and re-install the battery cables. Of course, clean everything with baking soda solution to neutralize any acid residue on top prior to re-install. NOW, you will have good contact for keeping the battery charged. FWIW.

For my Vette, I leave a Battery Tender hooked up. The MMs, I just run. Charghing system tester is coming for Christmas, I hope. Pleeeese, Santa?

Something's wrong. My MM sits that long sometimes and it always starts. I have old cars that sit sometimes more than a month and they still start, sitting in unheated garages or outside in the cold. A few weeks, should not drain a battery, and trickle charging it is a bandaid fix. Just get a damn new battery. You're putting a lot of unnecessary strain on your charging system trying to keep an expired battery alive.

I plan on getting a new battery anyway.
I just dont want to have this issue when i put the new one in.

my 76 sat outside for like 3 months with 7yr old batteries and fired right up. id say its time for a new one doomie, mines about shot as well. if your bat is relatively new, make sure nothing is draining it. i know you have an aftermarket head unit an i think you have an alarm. just throwing some ideas at ya.
 
You don't need to tend a battery if you park it for a couple weeks. Way overkill. You can do it if it makes you feel better but I don't tend my batteries and they last just as long as anyone else's.
 
Well i dont see what could be draining the battery. :confused:
Like i said it is the "ORIGINAL" so maybe its just time for a new one. :dunno:
 
Batteries always discharge, whether they are connected or not. Modern cars, like our MM's, will always draw a small amount of current. If you have a defective electrical sub-system, such as a leaking rear air suspension, it will increase the rate of discharge, since the pump will run more often.

A dirty top will increase the discharge. You can put a volt-meter on the top of a dirty battery, and get a voltage reading. A clean top will not have a voltage reading (between a post & the top).

If you don't keep a lead-acid battery charged, it will sulfate, and it's life will be shortened. It will discharge quicker in a warm environment. It will discharge slower in a cold environment, and be (more) subject to freezing and physical damage as it discharges.
 
I use Sears battery tender/trickle charger.
It appears it is no longer available.

It will do 6v and 9vdc, it's automatic, it has the option to harwire a connection to the battery and a quick connect end on the charger cord or just use the large alligator clips, and it is very small.

I have mine permanently wired in for convienence.

I use one on my motorcycles, tractor, and Marauder.

< $30

It is similar to this eBay listing:

your battery is definitely crapping out if its dying that fast. My car hardly moves anymore and i never have an issue starting it.

Buy a new battery (dont bother with the optima red top, its junk) and since you are probably storing your blingmobile for the winter, keep the battery out of the car and on a block of wood in the garage with a tender on it....
